MACHINE FOR MAKING CORRUGATED BOARD.

Specification of Letters Patent.

. Application filed January 20, 1915. Serial No. 8,196.

To all whom it may concern:

Be it known that I, BERG HEINRIoHS, a

resident of Anderson, in the county of Madi son and State of Indiana, have invented certain new and useful Improvements in Ma-' chines for Making Corrugated Board, of which the following is a full, clear, and exact description.

The invention relates to machines for makingcorrugated board and more particularly to mechanism for {cutting a continuous web into sheets of the desired size.

One object of the invention is to provide improved cutting mechanism which dispenses with the necessity of providing variable speed-gearing for operating it.

Another object of the invention is to provide mechanism which comprises cutters traveling synchronously with the web so that there will beno retarding effect upon 1 the web and so that stifi' corrugated board may be out without buckling the web.

A further object is .to provide improved I cutting mechanism which is adjustable to vary the length of the cut and is efiicient in use. V

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims atthe conclusion hereof.

In the drawings: Figure 1 is a side elevation of a portion of av corrugated board machine embodying the invention. Fig, 2 is a plan. Fig. 2* is a section taken op line 2*- a of Fig. 1. Fig. 2 is a detail of one end of the rotatable cutter-head and its operating lever. Fig. 3 is a side elevation of the cutting mechanism, the parts being shown in position assumed during the outstroke of the cutter carriage and before the sheet has been severed from the web. Fig. 4 is a similar view, showing the parts in position assumed, during the outstroke of the carriage, after the sheet ha een severed from the web. Fig. P is a detail section taken on line 4 -4 of Fig. 3. Fig. 5 is a central vertical section of the cutter, showing the parts in position corresponding to that shown in Fig. 3. Fig. .6 is a similar view, showing the parts in position corresponding to that shown in Fig. 4'. Fig. 6 is a detail section of the joint between the members of the shock-absorbing linkage for the cutter-carriage.

The improved cutting-mechanism is exemable endless'conveyers '10 and 11 between.

which the 'web, after it has been faced, is fed forwardly continuously and heated to cause the agglutinant for the second facing to set and to finish the board. In practice, it is customary to heat the web as it is fed by the conveyers, but since this mechanism forms no special feature of the presentinvention, it has not been illustrated. The delivery end of the upper conveyer 10, passes around sprockets 12 on a shaft 14,-which is mounted on a suitable frame 15 and the lower endless conveyer 11 passes around sprockets 16 on a shaft 17, which is also mounted on said frame. *These conveyers are adapted to be continuously driven by a power-pulley 18 which is loose on a shaft 19; and a suitable clutch 20 drives shaft 19 from said power wheel, while pinion 21 fixed 'on' The cutting mechanism is-designed to sep- 'a'rate sheets from the web during the continuous advance of the web in one direction and comprises a rotary cutter-head 27 to which is secured a knife or blade 28. This cutter-head is provided with endspindles 29, 30 which are journaled in bearings 31, respectively, on a reciprocable carri'age '32. A vertically disposed knife 33,

co-acting with the rotary knife 28,-to sever a sheet from the .web, is fixed to the end of the carriage. This carriage is reciprocably sustained upon members 15! of the frame 15' by rollers .33 which ride on said members respectively and a shaft 34 which is journaled in the carriage and has gears 35 therein which mesh with and are adapted to travel in racks 36, which are fixed to said frame-members. These rack and gear connections between the cutter carriage and the frame support one end of the frame and'insure .a' strictly parallel movement -of thecarriage in the direction of travel of the web.

cut-tersblade to travel in unison synchro- Intermittent reciprocating movement is imparted to the cutter-carriage to cause the cutter head before the cutter-carriage has" completed its outstroke so as to avoid buckling-or bending of the Web.

The mechanism for imparting intermittent reciprocatory movement to the cutter carriage comprises a beveled gear-wheel 37 which is fixed to the constantly rotating shaft 17 and meshes with a beveled gear 38 on a longitudinal shaft 39 which is suitably journaled in bearings on the frame and continuously drives a ear-wheel 40 fixed to the inner end thereo This gear wheel '40 meshes with a pair of oppositely disposed gears 41 and 42 both of which are looseupon a shaft 43 and are constantly driven in oppositedirections by gear 40. A clutch-- member 44 is slidably mounted on shaft 43 and is splined to the shaft so that when abutment 63 and 64 to avoid breakage of the the clutch-member rotates in either direction, said shaft will be correspondingly driven. The ends of member 44v are provided with clutch-teeth adapted to mesh with corresponding teeth onthe Wheels 41 42, respectively, so that shaft '43 may be driven in either direction according-to the positionof clutch-member 44. This'clutch member may also assume a neutral position ..ni'sm is to remain inoperative.

as shown, in Fig; 2, when the cutter mecha A gear-wheel 45'is' secured tothe inner end -of shaft 43 and meshes, with-airack 46 fixed .to. a reciprocable cutter operating bar 47.,- Theinner end of this bar isf'suit'a'bly mounted in a guide (not shown) on, frame 15 and the outer end is held vertically bythe spin-' dle 30on the cutter head-27. *A parallel 7 bar 49 is secured in spaced relation and beneath bar 47 to form 'a slot-or guideway- 50 for the-spindle 30. Bars 47 and 49 are secured together in spaced relation by blocks 51 and'52 which are bolted to said bars.

} Block 52 serves as an abutment for engagand between bars 47, 49 by abolt. 54 and I .plate 54, serves as an abutment for shifting first the spindle 30 and cutter-carriage "out- -ward1y. -The slot orguide 50 permits the desired-lost-motion between operating bar 47 and the cutter-head, so that the latter may remain stationary while'any desired portion of the Web is'being fed outwardly and until it'is necessary to operate the cutter-carriage. Mechanism-is provided for automatically shifting clutch-member 44 to cause it to be alternately shifted into operative relation with gears 41 and 42 so that gear 45, which nsaeao which is pivoted to the frame at 57 and is provided with an arm 58 carrying studs 59 extending into an annular groove on clutch 44. The inner end of this clutch-lever carries a rod 60 which is slidable therein and coil springs 61 and 62 are placed on this rod and between the headed ends thereof and oppositesides of the lever 56. An abutment 63, in the form of an adjustable screw, is adapted to strike one end of rod 60 to yieldingly shift, by means of spring 62, clutchmember 56 into engagement with gear 42 to operate the cutter-operating bar 47 outwardly and a block 64, which is adjustably secured to .bar 47,'is adapted to strike the other end of. rod 60 to shift clutch-lever 56 into position to meshwith gear 41 to operate bar' 147.. inwardly after each outstroke. Springs 61 and 62 provide for the yielding movement of the lever. responsive to the clutch teeth.

, Assuming the cutter mechanism to be in position indicated in Fig. 1 and the clutch end of the instroke, abutment 52 will engage spindle '30 and retract the cutter carriage, the latter movingin synchronism with the .bar 47. At the conclusion of the instroke, abutment '63 will shiftclutch lever 56 to cause shaft 43 to be driven by'gear 42 so that: bar 47 will be shifted outwardly in; synchromsm with the Web. During the outstroke, the cutter carriage will remain stationary until "abutment 53' engages spindle 30 and during the remainder of the out- ['stroke, the cutter-carriage will move in synchronism with the web as a result of the engagement of abutment 53 with the spindle.

'Duringthis operation of the outstroke, the

cutter head will be rotated to sever the sheet froniJthe web. Mechanism for effecting this ing spindle 30 of the.cutterheadto shift the rotary "movement of the cutter-head comprisesa lever 66 which is afli xed to the spindle 30 of the rotary cutter-head and carries a spring-pressed dog 67 at its upper end, and

an abutment68 which is stationary and secured to the frame 15. Dog 67 is pivoted to lever. 66 at 69 and is normally held to v.engagethe stop 70 on the lever by a spring 71, During the instroke of the carriage; theupper end ofdog 67 will ride under abutment 68, the spring permitting the dog to 'yield for this purpose. During the out- 7 stroke of the carriage, dog 67 will be detained by abutment 68, causing the spindle 30 of the'cutter-head to be rotated as the carriage is moving outwardlyuntil the dog .is free to pass under the abutment 68. This 28 to sever a sheet from the web while the carriage is moving in synchronism with the web. After the web has been severed and before the carriage reaches the end of its outstroke, dog 67 will have passed beneath and clear of abutment 68 and thereupon an abutment 72 fixed to the lower arm of lever 66 will strike a stop 7 3 in the form of an adju'stable screw, which is held on the. frame- 15 to cause the lever to be reversely rotated.

while the carriage is still moving in synchronism with the web and until the lower end of the lever 66 engages a stop 74 depending from the carriage. Thereupon, the cutterhead will be rotated into position to permit the web to pass under it while the cuttercarriage is stationary and during the retraction of. the cutter-carriage. Obviously, by adjustment of abutment 53, the time elapsing between the cutting'operations of knife 28, the length of the sheet severed from the web and the number of reciprocations may be readily varied so as to cut a web into sheets of different lengths. 1

' The end of spindle is squared, as at 30 for the application of a crank to operate the cutter manually. In practice, it sometimes occurs that adefective portion is to be cut from the web and by operating the cutter-head 27 manually this can be readily done, because of the lost motion connection between the cutter-operating bar and the spindles 30. Obviously, clutch-lever 56 may be manually shifted to bring the clutch- 1 member 44 to its neutral position or into engagement with either of the gears 41, 42, when desired in practice in starting the-machine.

In order to avoid shocking stresses upon the cutter-carriage at the end of it's reciprocatory movement, shock-absorbing linkages are provided between the supporting frame and the cutter-carriage, one of these linkages being disposed adjacent each side of the machine. Each of these linkages consists of a link 90 which is pivoted to the frame, as at 91, and a link 92, which is pivoted to the cutter-carriage at 93 and to the link 90 by a bolt 94. A spider washer 95, having spring arms, is interposed between the bolt and one of the links to frictionally press the links together. As a result, the links will be frictionally pressed together to cushion the movement of the carriage and absorb the shock at the end of the'movements ofthe carriage. The cutting-mechanism will operate intermittently to successively cut. the web without attentionupon the part of the operator, because .the reciprocations of the cutter-operating bar are automatically shifted by the abutments and the clutch. p

The invention thus ex'em lifies an improved cutter-mechanism or corrugated ing in a plane parallel to the line of travel ing which the carriage will move synchronously with the web and also ermits ready adjustment for varying the ength of the cut from the web.- The cutting-mechanism is simple in construction and eflicient in operation.

' The invention is not to be understood as "restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit. and scope of the'invention.

Having thus described the invention, what I claim as new and desire to secure by LettersPatent, is: 1
